Feudalism, unlike capitalism, arose from multiple societies and civilizations. While capitalism's origins can be traced to, depending on who you ask, either Italian city-states or the Dutch Republic, the Chinese Dynasties, the Carolingian Empire, the various Caliphates, the Delphi Sultanate, and so on all independently had a feudal mode of production. So, it's more proper to speak of feudalisms than feudalism. And just like capitalism has distinctive stages (mercantile, industrial, financial, neoliberal), the feudalisms of long-lasting empires like China also had distinctive stages. One book I read that examines Chinese feudalism splits Chinese feudalism into three stages: feudal manorialism, ascending feudal landlordism, and declining feudal landlordism. Between the multiple feudalisms, many of which would have multiple stages with their feudalisms, it's obviously going to be hard to have a pithy definition that accurately describes every single version and stage of feudalisms.

Still, there are going to be interesting parallels between the feudalisms because it's still feudalism in the end. For example, the Chinese also had a knightly class, a class that were originally warriors serving a liege who then transitioned into a land-owning aristocratic class. The main difference is that the Chinese version transitioned again from an aristocratic class to a literati scholar-official class that worked as a bureaucrat within the imperial bureaucracy. This was due to the combination of feudal landlordism placing less of a premium on inheriting land (the main difference between feudal manorialism and feudal landlordism as defined by the book is that you can buy and sell land under feudal landlordism but not feudal manorialism), the size of the imperial bureaucracy which required an army of bureaucratic officials, and the implementation of a meritocracy through the imperial examinations that tested your knowledge of the Confucian classics and other literary works.
